Protect Multiple objects from accidental deletion via AD PowerShell

First of all open PowerShell and run “Import-Module activedirectory”

Now run the following but obviously change the DN name so that it points at the OU relevant for your domain.

Get-ADobject -Filter * -SearchBase “OU=Users,DC=Domain,DC=com” | Set-adobject -ProtectedFromAccidentalDeletion $true

All users in the OU should now be protected from accidental deletion
